Bismillahirrahmanirrahim. This might be quite late but, the intention is to show you readers the tradition that we have here in SMKA Segamat. For the past two years, I was invigilating PMR but this year, I got da chance to witness the tradition of this school before entering the exam hall. Upon entering the hall, one representative will recite the Azan - prayer call.
After that, they recited the Doa. At this time, we can see how the students are very enthusiastic and eager to enter the exam hall as a 'warrior' :)
and of course, once you are in the hall...individual prayer is also important.
